Dichloromethane is an organic compound with the chemical formula CH2Cl2. It is a colorless and transparent liquid with an irritating odor similar to ether. Slightly soluble in water, soluble in ethanol and ether, it is a non flammable low boiling solvent under normal usage conditions. When its vapor becomes high concentration in high-temperature air, it will generate a weakly combustible mixed gas, commonly used to replace flammable petroleum ether, ether, etc.
The main uses are:
1. Used for grain fumigation and refrigeration of low-pressure refrigerators and air conditioning devices.
2. Used as a solvent, extractant, and mutagen.
3. Used in the electronics industry. Commonly used as a cleaning and degreasing agent.
4. Used as a local anesthetic for dentistry, a refrigerant, a fire extinguishing agent, and a degreaser and film remover for cleaning metal surface coatings.
5. Used as an intermediate in organic synthesis.
